To all. whom it may concern:

Be it known that I, ALEXANDER OJSCHU- MAN, a citizen of the United 'Statearesiding at Louisville, in thecounty of J efi'erson and State of Kentucky, have invented certain new anausenu- Improvements in Waof which the following is a specification.

' This invention relates to fiushing apparatus for water closets which are located outside of dwellings, andits object is to provide a structure whereby all danger of freezing of the apparatus is'eliminated, and clog? ging of the. discharge pipe avoided. i v

' The invention also has 'for its object to the closet perfectly sanitary.

The objects stated are attained] by means it of a novelcombination and arrangement of parts ton be Fhereina'fter described and claimed, and inorder'that the samemay be better understood, reference is had to the accompanying drawing forming apart of this specification; I v

'In the'drawing, Fi ure 1is an elevation of the apparatus, part ly in section, and Fig. '2 is a similar View. of a fragment of the apparatus, with certain parts'in another position from-that shown in Fig. 1.

The preferred embodiment ofthe'invention has beenillustrated, but it will be understood that various changes and modifica- 'tion may made without a departure from the spirit and scope of the invention as claimed hereinafter. I

' 1 The reference numeral 5 in the drawing denotesja closet bowl provided with a pivoted seat 6, and adapted tobe flushed from a; tank 7 obtaining a water supply through a pipe 8 connected to a suitablesource. The tank is provided with a float-controlled inletvalve 9' which is closed by a lever 10. carrying a float 11. 'When a predetermined water level in the tank is reached, thelever 10 presses the valve 9 closed. The water is discharged fromthe tank into the bowl 5 through anoutlet pipe-12,'anordinary ball 'flushingvalve 13 being also provided. This 'valve is connected to a lever lhprovided with a depending'actuating rod15.

In the pipe 8 isi'nterposed-a three-way valve 16 having a drain ou'tlet17, and an actuating arm 17, to which" latter a rod 18 -''is connected} This rod' extends alongside the bowl 5.; and its upper end is in the path the water.

turn, is arranged to dischargeiinto are- "eeiving chamber 23 having an outlet 2 1 prol The outlet end of the bowl'5 is provided [with a closure in'the iform of a pivoted flap valve26 connected by a link 27 to the seat 6 in suehja manner that said valve is opened "when the seat is swung down for use, as V ShownTiniFigf2; When the seat is up, the

'val veis closed, in,whi ch latter positionit "seats over the 'bowl outlet" and forms an effective seal'to prevent escape of sewer gas.

The outlet end of the second bowl 22 is I provided with a closure 28, which latter is also in the form offla pivotedfiapfvalve. This valve is designed .to, close the outlet. of T the bowl 22 when the'seat 6 isdown and the closet" is in use. .As shown in Fig. 1, the

valve 28 has allaterally extending arm 29 to which X is connected a vertically extending and 30 which projects from the chamber 23 and extends alongside the bowl 5so as to locate its upper end in the path of an abutment 31 on the seat 6. A, spring 32 is also connected to'the arm 29 for opening the valve When the *seat 6 is lowered for use,the abutment-.61 strikes the upper end of the rod 30 ,'and the latter,as it 'oves The rod 30 is fiexible's'o that it may be tripped ofi' the abutment 31, this being'done a bell-crank lever 33fhaving one of its ends connected tothe rod '15, and its other end located alongside the rod 30. Assuming Inent ofthe abutment 31 with the rodf30', if.

open the flushing valve 13,"th,e bell crank leveri33f'forces the 'IO( l '30 sidewise clearof' thejabutment 3'1, whereupon the spring. 32

opens'fthe valve The purpose of this operation will be presently 'made cl'ear.,l"

of an abutment'19 on the seat 6, so located The seatfi is provided-with a spring catch 34itor holding the same down, said catch engaging a keeper lug 35 on'the bowl 5.

' Whenthe catch is released, the seat is auto.-

unseats the flushing valve 13.

matically raised by a spring 36 connected to its rear end as shown in Fig. 2.

The tank 7 also has an auxiliary outlet 37 connected to the flushing pipe 12, and pro vided with a floatcontrolled valve '38. When the tank 7 is empty, the float 39 ot' the; valve 38 is down, and said valve is open. It will therefore be seen that a small supply of water flows into the bowl 5 while the tank is filling, and as the float 39 rises and closes the valve 38, this flow ceases.

From the inlet valve 9 extends a hookshaped stem engageable by the float lever 10 when the float 11 is down, this being for the purpose of opening the valve 9 to permit the pipe 8 to drain.

Fig. 1 shows the normal positionoii the parts. The bowl 5 is closed tothe bowl 2E2 by the valve 26, and the valve 28 is open. Upon lowering the seat 6, the valvef 26 swings open as shown in Fig, 2, and the valve 28 is closed as hereinbetore descrlbed.

The valve 16 is also opened to admit water into the tank 7 and when a predetermined water level is reached, the valve 9 is permitted toclose by the float lever 10. When the water commences to flow intothe tank, a small quantity escapes through the pipe 37 and flows through thepipe 12 into the bowl 5 and passes from the latter into the bowl 22, in which it collects above the valve 28, and as said valve is closed, the water preventsffecal matter from sticking thereon. The flowof: water through the pipe 37 ceases when the valve 38 closes, and the: tank then continues to fill until. the valve 9 closes,

To flush the bowl 5, the rod 15 is pulled downwardly, which, through the lever 14, 7 At the same time, the hell-crank lever 33 pries the rod away fromthe abutment 31, whereupon the spring 32 opens the valve 28, and as the valve 26 already'open, the contents of the bowls 5 and 22 can escape: into the chamber 23- and passlinto the sewer connection 25.

When the seat is raised, the abutment 19 leaves thestem 18, whereupon the spring 20 places the valve 16 in closed position, and

establishes communication between the pipe 8 and the drain outlet 17 and as the valve 9 was opened by the engagement of the float lever 10 with the stem 40 when the tank emptied, any water remaining in the pipe 8 can escape, so that all danger of freezing is eliminated. The valve 16 will be located Before the seat 6:can be swung upward by the spring 36, itis necessary to disengage the catch Mr-from the keeper 35. The'flushing operation must, be effected whil the seat ,is down, and hencethecatch prevents the closure to open.
